To Be Happy! 1973

Directed by Lev Tsutsulkovsky

A young fitter at a bus stop accidentally pushed a girl, and she fell. This is how they met, although both are dating their other halves. One day, he gathers friends to build his dream house overnight. He found her at a roadside restaurant, and they walked through the forest all night, and in the morning he puts her in the car and takes her away.
